Atmosphere 4.0.44

Added

• predictable-AI primitives — three framework-level capabilities that close gaps Bonér's "Herding LLMs" deck flagged for distributed-system reliability, all declared on every framework runtime so the matrix closes without @Beta shims:
  • BUDGET_ENFORCEMENT (a4fae39464) — new AiBudget value record (max input / output / total tokens, max steps, max wall clock) installed via pipeline.setDefaultBudget(...) or per-request ai.budget metadata. BudgetCapturingSession decorator slots into the AiPipeline session-decorator stack between metrics and guardrail layers; on breach it routes a typed AiBudgetExceededException extends AiException through session.error(...) and short-circuits subsequent send / usage / progress / emit / complete calls so the wire protocol's "one terminal frame" invariant holds. Distinct from org.atmosphere.ai.budget.StreamingTextBudgetManager (long-running per-tenant cumulative spend); this capability is the per-call death-spiral guard. 13 new unit tests cover every breach reason, default vs. per-request override, and the post-trip swallow. Wall-clock limits trip universally; token / step limits depend on TOKEN_USAGE (every runtime except Spring AI Alibaba honors both).
  • CONFIDENCE_SCORES (a4fae39464) — new AiConfidence record with OptionalDouble aggregate, List<TokenLogprob> tokens, and Source enum (LOGPROBS_NATIVE / MODEL_REPORTED_FIELD / HEURISTIC). StreamingSession.confidence(AiConfidence) default method auto-emits ai.confidence.aggregate / .source / .tokens metadata mirroring the usage(TokenUsage) convention; DelegatingStreamingSession gains the matching forwarding override. Universal model-reported path via the new AiConfidenceElicitation plus the ConfidenceCapturingSession decorator: pipeline appends an opt-in cue to the system prompt, decorator parses the model-emitted {"confidence": 0.x} field on stream completion (same regex shape as the existing ConfidenceThresholdGuardrail) and fires session.confidence ahead of the terminal frame. Decorator self-suppresses when a runtime already invoked confidence(...) directly with LOGPROBS_NATIVE. Skipped when structured-output mode is in play because the schema parser owns the response shape — callers add a confidence field to their record schema in that mode. 14 new unit tests cover record validation, the elicitation cue, parser fallbacks, runtime-explicit override, per-request override of the pipeline default, and the structured-output skip.
  • PASSIVATION (a4fae39464) — new AgentSnapshot record in modules/ai (persistable subset of AgentExecutionContext — message, system prompt, identity columns, history, JSON-clean metadata, response type name, reason, paused-at). New AgentPassivation static helper in modules/checkpoint with passivate(runtime, ctx, store, reason): String, resume(runtime, store, id, externalSignal, base, session), and loadSnapshot(store, id). resume merges the snapshot onto a caller-supplied base context (which carries the runtime references — tools, memory, listeners, retry policy — that don't survive a JVM restart) and re-runs runtime.execute(...); base wins on metadata-key collision so caller-injected refs (e.g. trace context) are not clobbered by stale snapshot values. Helper lives in modules/checkpoint rather than on AgentRuntime itself because modules/ai → modules/checkpoint introduces a ai → checkpoint → coordinator → ai cycle; the reverse direction is acyclic. Capability flag declared on every runtime — flag advertises "this runtime cooperates with AgentPassivation," honest because every runtime threads context.history() through its dispatch path so a resumed call observes the same conversation the paused call saw. 10 new unit tests cover snapshot round-trip, resume flow with external signal, signal-less replay of pending message, missing-checkpoint errors, metadata filtering (non-String values dropped pre-snapshot), metadata merge precedence, unique IDs across passivations, and null-arg rejection.

Changed

• AiCapability enum gains 3 entries — total 20 capabilities (was 17). AbstractAgentRuntimeContractTest.expectedCapabilities() pin updated for all 9 framework runtimes: BuiltIn, Spring AI, LangChain4j, ADK, Embabel, Koog, AgentScope, Spring AI Alibaba, Semantic Kernel. BuiltInAgentRuntime capability count test bumped from 13 to 16. Capability matrix in modules/ai/README.md extended with BE / CS / PSV columns plus a "Predictable-AI primitives" section documenting each capability's decorator placement, source enum, and runtime-by-runtime caveats (Spring AI Alibaba's BUDGET_ENFORCEMENT is wall-clock-only because the runtime does not surface TOKEN_USAGE).

Tests

• Playwright e2e coverage for the predictable-AI primitives (4be20c240c) — ai-budget-circuit-breaker.spec.ts, ai-confidence-elicitation.spec.ts, ai-passivation.spec.ts exercise the full AiPipeline session-decorator stack through Atmosphere's wire transport. Each spec drives a dedicated test handler (BudgetCircuitBreakerTestHandler / ConfidenceElicitationTestHandler / PassivationTestHandler) registered in AiFeatureTestServer so the harness sees AiBudgetExceededException on the wire's error frame, the ai.confidence.aggregate / .source / .tokens metadata frames the confidence(...) default sink emits, and the snapshot/resume round-trip across two sequential WebSocket connections. modules/integration-tests/pom.xml bumps atmosphere-checkpoint from test to compile scope so PassivationTestHandler can call AgentPassivation directly. modules/integration-tests/playwright.config.ts registers the three new spec project entries.

Fixed

• CLI standalone-scaffold compile against the released parent POM (7383eb0ee2) — twenty samples/spring-boot-*/pom.xml files now declare <netty.version>4.2.13.Final</netty.version> in their own <properties> block so the sample is self-contained: scaffold-then-compile against the released org.atmosphere:atmosphere-project:4.0.43 parent (which predates the netty bump and therefore does not declare netty.version) no longer fails with Non-resolvable import POM: io.netty:netty-bom:pom:${netty.version}. cli/e2e-test-cli-runtime.sh also fixes a long-standing comment-vs-code drift: the script was exporting ATMOSPHERE_CLI_VERSION while cli/atmosphere only ever read ATMOSPHERE_VERSION_OVERRIDE, so the SNAPSHOT-against-SNAPSHOT lane silently degraded to release-pin coverage. Renaming the export aligns the script with the CLI's actual contract.

Atmosphere 4.0.43

Added

• per-request runtime extension helpers (f1493c3f9c) — small attach(context, ...) / from(context) helpers (modeled on the existing CacheHint) that let callers stash framework-native composition objects in AgentExecutionContext.metadata(), so a runtime can apply them per-request without growing the unified AgentRuntime SPI with framework-specific knobs. Runtimes covered: SpringAiAdvisors (Spring AI Advisor chain — RAG / memory / guardrails / observability), LangChain4jAiServices (LangChain4j AiServices / TokenStream), KoogStrategy (Koog AIAgentGraphStrategy DSL), AdkRootAgent (ADK BaseAgent / SequentialAgent / ParallelAgent / LoopAgent topology), and ToolLoopPolicies (per-request ToolLoopPolicy honored by BuiltInAgentRuntime's OpenAI-compatible tool loop). The other shipped runtimes (AgentScope, Embabel, SemanticKernel, SpringAiAlibaba) do not yet have a per-request bridge — Embabel got native streaming via StreamingPromptRunnerBuilder.streaming().generateStream() in the same merge but no sidecar. Also added: AgentLifecycleListener.onModelStart / onModelEnd / onModelError hooks with fireXxx fan-out helpers, and AiEventForwardingListener adapter that translates lifecycle hooks to wire-format AiEvent.Progress frames (opt-in via context.withListeners(...)). Each bridge ships with a unit-level *BridgeTest proving the runtime honors the sidecar.

Fixed

• Quarkus extension closes the /api/console/info parity gap — the bundled Atmosphere Console UI gets the same subtitle / endpoint / runtime / mode payload it gets from the Spring Boot starter, instead of falling through to the Vue defaults on a 404. New AtmosphereConsoleInfoServlet (HttpServlet, registered at build time via a second ServletBuildItem mapped to /api/console/info) reuses the same package-prefix mode-detection heuristic as AtmosphereConsoleInfoEndpoint (org.atmosphere.{ai,agent,coordinator}.* → "ai", anything else including ManagedAtmosphereHandler → "broadcast"). Endpoint auto-detection prefers the canonical /atmosphere/ai-chat when registered (samples like quarkus-ai-chat ship multiple @AiEndpoints), then /atmosphere/agent/*, then any other /atmosphere/*. New config keys quarkus.atmosphere.console-subtitle and quarkus.atmosphere.console-endpoint mirror the Spring atmosphere.console-subtitle / atmosphere.console-endpoint properties. JSON is hand-rolled so the runtime POM stays Jackson-free; AgentRuntimeResolver is reached via reflection so the servlet keeps no compile-time link to modules/ai. Empirically verified in chrome-devtools against quarkus-ai-chat — /api/console/info now returns {"subtitle":"Runtime: langchain4j","endpoint":"/atmosphere/ai-chat","runtime":"langchain4j","mode":"ai"}, the Vue Console shows the runtime label in the header subtitle, and the cross-tab isolation matrix continues to pass on the Quarkus leg.
• bundled Atmosphere Console now auto-detects AI vs. broadcast endpoints (c1e8e36c7b) — /api/console/info adds a mode field ("ai" for @AiEndpoint / @Agent / @Coordinator, "broadcast" for @ManagedService chats); AtmosphereConsoleInfoEndpoint#detectMode classifies via the registered handler's package prefix (org.atmosphere.{ai,agent,coordinator}.* → ai, everything else including ManagedAtmosphereHandler → broadcast), so the check stays compile-time independent of modules/ai and modules/agent. The Vue frontend swaps empty-state copy ("Start a conversation" + "AI assistant" → "Start a broadcast" + "every connected client on this endpoint will receive it") and the default subtitle ("Runtime: " → "Multi-client broadcast chat") based on the detected mode. Closes the misleading-UI half of the cross-tab leak follow-up: pre-fix, spring-boot-mcp-server and spring-boot-otel-chat rendered the AI-assistant copy despite being broadcast-shared by design. Empirically verified in chrome-devtools against both broadcast samples and spring-boot-ai-chat. Per-sample atmosphere.console-subtitle overrides still win over the mode-aware default. 5 new contract tests in AtmosphereConsoleInfoEndpointModeTest pin the four classification paths plus the override interaction.
• cross-tab isolation matrix extended from 11 → 15 samples (c1e8e36c7b) — adds quarkus-ai-chat (cross-runtime parity, proves the targeted-dispatch fix from 1fbb0958f0 survives Quarkus's distinct QuarkusJSR356AsyncSupport path), spring-boot-checkpoint-agent (@Coordinator with analyzer/approver fleet + checkpoint store), spring-boot-ms-governance-chat (@AiEndpoint with @AgentScope classification interceptors stacked in front), and spring-boot-channels-chat (omnichannel @AiEndpoint with Telegram/Slack/WhatsApp/Messenger channel-bridge adapters). New fixture entries in e2e/fixtures/sample-server.ts for the checkpoint and ms-governance samples; quarkus-ai-chat reuses the existing fixture. Out-of-scope docstring corrected to remove spring-boot-channels-chat (it's actually an isolated @AiEndpoint, not a broadcast chat) and to explicitly tag spring-boot-a2a-agent as out-of-scope (A2A JSON-RPC has no two-tab Console scenario). All 15 cases pass locally in 3.5m.
• OpenAiCompatibleClient Javadoc placement broke JDK 26 strict mode (28703ea064) — two stacked Javadoc blocks on forwardResponsesApiUsage raised documentation comment is not attached to any declaration under -Xlint:all -Werror on JDK 26 (silent on JDK 21). Merged into a single coherent block; CI: Core (JDK 21/26) green.
• cli/samples.json and cli/atmosphere template map referenced deleted spring-boot-embabel-chat sample (3a9373e875) — cli/test-cli.sh failed with "samples missing README.md: spring-boot-embabel-chat". Entry removed from samples.json + template-map case statement.

Atmosphere 4.0.42

Added

• atmosphere-verifier — plan-and-verify (Meijer "Guardians of the Agents") New module modules/verifier/ + sample samples/spring-boot-guarded-email-agent/ — sealed Workflow AST, ServiceLoader-discovered PlanVerifier chain (Allowlist/WellFormed/Capability/Taint/Automaton/SmtChecker SPI), @​Sink + @​RequiresCapability scanners, PlanAndVerify orchestrator, WorkflowExecutor with partial-env on failure, verify CLI; sample REST + UI exercises the inbox-exfiltration scenario end-to-end (refused before any tool fires) — 74 unit + 4 boot + 6 Playwright tests, all CI green on the feature branch.

Fixed

• fail-closed verifier empty-chain, JSON-escape govern. deny, deflake wasync PlanAndVerify.withDefaults + VerifyCli runChain throw / emit chain-empty violations when ServiceLoader yields no providers (P1: silent fail-open under shading / native-image / fat-jar relocation); governance-deny tool result routes every interpolated field through ToolBridgeUtils.escapeJson via a new buildGovernanceDenyJson helper (P2: backslash/newline/control char break); ChatIntegrationTest.socketStatusTransitions polls for status transition rather than asserting in the same instant the OPEN handler fires (release-pipeline timing flake). 5 new verifier tests + 6 governance-JSON tests.

Changed

• drop org.json:json — Jackson 3 only (CVE hygiene) RoomProtocolCodec + SimpleRestInterceptor migrated to tools.jackson; brace-balanced reader preserves SwaggerSocket header/body chunk semantics; ALLOW_SINGLE_QUOTES kept for wire compatibility; org.json removed from parent + 3 spring-boot samples.
• bump version to 4.0.41
• prepare for next development iteration 4.0.42-SNAPSHOT

The matrix closes on 4.0.43: all eight framework runtimes have a sidecar — SpringAiAdvisors (Spring AI Advisor chain — RAG / memory / guardrails / observability), LangChain4jAiServices (LangChain4j AiServices / TokenStream), KoogStrategy (Koog AIAgentGraphStrategy DSL), AdkRootAgent (ADK BaseAgent / SequentialAgent / ParallelAgent / LoopAgent topology), EmbabelPromptRunner (UnaryOperator<PromptRunner> customizer applied AFTER default wiring), AgentScopeAgent (per-request ReActAgent), SemanticKernelInvocation (per-request InvocationContext — unlocks KernelHooks, withMaxAutoInvokeAttempts, custom PromptExecutionSettings), SpringAiAlibabaRunnableConfig (per-request Alibaba RunnableConfig for threadId/checkPointId/streamMode/metadata/store), plus the cross-runtime ToolLoopPolicies honored by BuiltInAgentRuntime's OpenAI-compatible tool loop. Initial five sidecars landed via f1493c3f9c; the remaining four runtimes plus the lifecycle hook fan-out below landed via eec98890fe. Also added: AgentLifecycleListener.onModelStart / onModelEnd / onModelError hooks with fireXxx fan-out helpers wired in all 8 framework runtimes (was Built-in only), and AiEventForwardingListener adapter that translates lifecycle hooks to wire-format AiEvent.Progress frames (opt-in via context.withListeners(...)). Each bridge ships with a unit-level *BridgeTest proving the runtime honors the sidecar.

Fixed

JSON is hand-rolled so the runtime POM stays Jackson-free; AgentRuntimeResolver is reached via reflection so the servlet keeps no compile-time link to modules/ai. Empirically verified in chrome-devtools against quarkus-ai-chat — /api/console/info now returns {"subtitle":"Runtime: langchain4j","endpoint":"/atmosphere/ai-chat","runtime":"langchain4j","mode":"ai"}, the Vue Console shows the runtime label in the header subtitle, and the cross-tab isolation matrix continues to pass on the Quarkus leg.
• bundled Atmosphere Console now auto-detects AI vs. broadcast endpoints (c1e8e36c7b) — /api/console/info adds a mode field ("ai" for @AiEndpoint / @Agent / @Coordinator, "broadcast" for @ManagedService chats); AtmosphereConsoleInfoEndpoint#detectMode classifies via the registered handler's package prefix (org.atmosphere.{ai,agent,coordinator}.* → ai, everything else including ManagedAtmosphereHandler → broadcast), so the check stays compile-time independent of modules/ai and modules/agent.

Closes the misleading-UI half of the cross-tab leak follow-up: pre-fix, spring-boot-mcp-server and spring-boot-otel-chat rendered the AI-assistant copy despite being broadcast-shared by design. Empirically verified in chrome-devtools against both broadcast samples and spring-boot-ai-chat. Per-sample atmosphere.console-subtitle overrides still win over the mode-aware default. 5 new contract tests in AtmosphereConsoleInfoEndpointModeTest pin the four classification paths plus the override interaction.
• cross-tab isolation matrix extended from 11 → 15 samples (c1e8e36c7b) — adds quarkus-ai-chat (cross-runtime parity, proves the targeted-dispatch fix from 1fbb0958f0 survives Quarkus's distinct QuarkusJSR356AsyncSupport path), spring-boot-checkpoint-agent (@Coordinator with analyzer/approver fleet + checkpoint store), spring-boot-ms-governance-chat (@AiEndpoint with @AgentScope classification interceptors stacked in front), and spring-boot-channels-chat (omnichannel @AiEndpoint with Telegram/Slack/WhatsApp/Messenger channel-bridge adapters). New fixture entries in e2e/fixtures/sample-server.ts for the checkpoint and ms-governance samples; quarkus-ai-chat reuses the existing fixture. Out-of-scope docstring corrected to remove spring-boot-channels-chat (it's actually an isolated @AiEndpoint, not a broadcast chat) and to explicitly tag spring-boot-a2a-agent as out-of-scope (A2A JSON-RPC has no two-tab Console scenario). All 15 cases pass locally in 3.5m.
• OpenAiCompatibleClient Javadoc placement broke JDK 26 strict mode (28703ea064) — two stacked Javadoc blocks on forwardResponsesApiUsage raised documentation comment is not attached to any declaration under -Xlint:all -Werror on JDK 26 (silent on JDK 21). Merged into a single coherent block; CI: Core (JDK 21/26) green.
• cli/samples.json and cli/atmosphere template map referenced deleted spring-boot-embabel-chat sample (3a9373e875) — cli/test-cli.sh failed with "samples missing README.md: spring-boot-embabel-chat". Entry removed from samples.json + template-map case statement.
